3D Printing

Engineering polymers and fiber-reinforced materials — functional, structural, and production-ready.

3D printing supports rapid prototyping and product development in Malmö, from material selection to testing and iteration. Serving businesses in Skåne and southern Sweden.

A printed enclosure can be combined with laser-cut prototype parts in transparent acrylic, such as front panels and display windows. PVC/Vinyl belongs to 3D printing here and is never laser-cut or laser-engraved.

Production Equipment: High-Speed, High-Reliability 3D Printing

3D printer farm (Bambu Lab X1C)

My workshop is built around Bambu Lab X1C printers—by choice. After testing newer generations, I still prefer the X1C platform because it hits the sweet spot of what actually matters in production: speed, consistency, and robustness.

The X1C’s lightweight print head enables exceptionally fast acceleration and travel moves, translating to very short cycle times without sacrificing detail. Just as importantly, the platform is mechanically dependable and less prone to the “fragility-by-complexity” that often comes with more elaborate systems.

Always-Ready Materials Workflow

To keep turnaround times tight, I run Automatic Material Systems with 17 filament spools loaded and ready at all times, allowing quick switching between materials and colors without interrupting production flow.

For moisture-sensitive polymers, I maintain multiple drying stations and continuous humidity monitoring—both in storage and during printing. This ensures stable extrusion, clean surfaces, and strong layer bonding, especially in demanding technical materials.

Result: fast lead times, repeatable quality, and a setup designed for real-world reliability—not just specs on paper.

Materials

  • PPA-CF / Fiber reinforced polymers
  • PA / PA-CF / PA-GF
  • PC, ASA, ABS
  • PETG
  • TPU (flexible)
  • Foamed TPU / foam rubber
  • PP (polypropylene)
  • PVC / Vinyl

Foamed TPU

Foamed TPU is offered for soft, foam-like development parts. The documented print trials explore variable hardness within one part and open or closed cells depending on the application. The result needs to be assessed and tested for its intended use.

Polypropylene (PP)

PP is available for tough, flexible parts and functional tests. The documented examples show walls of 0.2 mm in the thin part and 0.75 mm in the larger cup. These are specific examples, not universal minimum-wall guarantees.

Food-contact suitability must be assessed for the material, finished part and intended use; a material description does not certify every printed part.

Lambretta Quattrini M210 Inlet Reed Manifold

Material: PAHT-CF — carbon-fiber reinforced polyamide with high temperature resistance.

Inlet Stuffer for Lambretta Quattrini Cylinder Kits (Mikuni TM(X) 27mm)

If you’ve fought with the original inlet rubber, you already know the problem: inconsistent sealing, weak material, and parts that don’t hold up—especially with modern fuel blends. This inlet stuffer is the reliable, performance-focused alternative: better sealing, smoother flow, and built to survive real riding.

Built for performance — engineered for durability

  • Made from high-temperature carbon-fibre filled nylon for heat resistance while still retaining enough “give” to avoid brittleness around fasteners
  • Designed to be fuel/alcohol resistant to handle today’s pump fuels
  • Acts as a heat-insulating spacer, helping keep carb temperatures down
  • Flow-optimized geometry (not just a flat plate)

CFD-optimized internal shape

  • CFD-optimized internal shape to support smooth, laminar airflow with minimal disturbance
  • Outlet is matched to the non-circular Mikuni flow path to reduce obstruction where it matters most

Designed for sealing and long-term stability

  • Print orientation and sealing surfaces are engineered to come off the printer with the right finish (only basic support removal needed)
  • Post-print cured to maximize layer adhesion and stability under heat and clamp load
  • Integrated stainless M8 Nyloc nut pockets for secure, vibration-resistant fastening and excellent thread quality
  • Intended for use with a gasket against the cylinder for added sealing confidence

Proven on the road

This isn’t a bench prototype. The design has been run for ~3500 km, including long, hard rides in hot conditions, with no deterioration or issues.

Fitment and customization

Developed for Mikuni TM(X) 27mm using the original Mikuni inlet rubber interface. The CAD is parametric, making it straightforward to adapt for 30mm Mikuni or other carburettors on request.
